Floating wetlands a promising way to decrease wastewater emissions: new research

Treating dirty waste water solves one environmental problem but creates another by releasing large amounts of climate emissions. As microorganisms break down sewage, they release carbon dioxide, methane and nitrous oxide – three potent greenhouse gases. Our new research found a surprisingly simple way to cut greenhouse gas emissions from open wastewater treatment lagoons: growing plants on buoyant rafts. Water treatment companies have made progress in reducing emissions from their operations,…
